On Tuesday night’s True Tori special Tori Spelling claimed she didn’t know if Dean McDermott had cheated on her with more than one woman because she didn’t want to know the answer, but RadarOnline.com has exclusively learned he told his actress wife months ago that he had sexual trysts with at least five other women.

“He was forced to finally admit the truth to Tori,” the insider previously said.

“Making matters worse, Dean admitted to not always using protection during the encounters. It’s the ultimate betrayal for Tori and she probably won’t be able to ever forgive him for that. It’s one thing to cheat, but another to have unprotected sex.”

Spelling did address the accusations of bad karma, as both she and McDermott had originally cheated on their respective spouses to be with each other. “What happened was hurtful to other people,” she said, “but you can’t help when you fall in love with someone.”

Later, the ex-Beverly Hills 90210 star, 41, said she felt bad for 47-year-old McDermott¹s first wife, Mary Jo Eustace, however, “I don’t see it as I broke up his marriage, that was his decision.

“I knew he was married and I was thinking this was wrong but we fell in love — there was that connection, it was instant. But I always said at the time, if this should ever happen to me, I don’t think I’d blame the woman. I would blame my husband. I still, to this day, I don’t blame Emily [Goodhand]. I blame Dean completely.”

Our source adds, “If Tori knew he didn’t cheat on her with more than one woman, she would have been able to ask Dean on camera, because that is something that she could brag about it. Or Dean could have just said there was no one else besides Emily Goodhand, but he couldn’t because it would have been a lie.”
